PRE SSURE-REGULATING VALVE.

SPECIFICATION forming part of Letters Patent No. 641,120, dated January9, 1900.

Application filed April 29, 1899. Serial No. 714,967. (No model.)

T0 at whom it may concern.-

Be it known that I, GEORGE KETTENRING, a

citizen of the United States, residing at Newark, in the county of Essexand State of New Jersey, have invented certain new and usefulImprovements in Pressure- Regulating Valves; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,and to letters of reference marked thereon, which form a part of thisspecification.

The objects of this invention are to provide a convenient, simple andeffective apparatus for automatically testing, regulating, anddetermining the pressure exerted by the gases in casks of beer or othersimilar liquid during fermentation, to provide such a device that may beconveniently and etfectively used in admitting air to the casks when itis desired to do so in racking off the beer orother liquid, and tosecure other advantages and results, some of which may be referred tohereinafter in connection with the description of the working parts.

The invention consists in the improved pressure-regulating valve and inthe arrangements and combinations of parts of the same, allsubstantially as will be hereinafter set forth, and finally embraced in.the clauses of the claim.

Referring to the accompanying drawings, in which like letters ofreference indicate corresponding parts in each of the several views,Figure l is a central vertical section of my improved apparatus, takenon line at, Fig. 2. Fig. 2 is a plan of the same, and Fig. 3 is a detailview of a certain valve.

- In said drawings, a indicates a stand-pipe threaded at its lower end,as at a, to screw into a suitable bushing in the cask or to be otherwisesecured thereto. At a higher point said stand-pipe is provided with aside branch or tube 1), having a stop-cock b, by means of which air maybe admitted to the cask when necessary in racking. Above the said branchtube b'the vertical stand-pipe a is provided with a stop-cock c, bywhich communication with the upper parts, to be hereinafter de scribed,may be cut off. Near its upper end the stand-pipe is exteriorlythreaded, as at (L to receive a cup-shaped casting d, said casting 61being provided at its bottom with a tubular projection e,correspondingly threaded to screw upon the stand-pipe. The bottom of thecup-like casting d is perforated concentric with the extension 6, andthrough said perforation the upper end of the standpipe a projects intothe cup 01 a short distance, being provided at the extremity withknife-like edges, forming a seat for a valve f.

The cup-like casting cl provides a more or less large receptacle forwater or other valvelubricating fluid, and interiorly said cup-likereceptacle has an integral upward projection g, which is tubular,concentricwith the outer and lower extension 9, and interiorly threadedto receive the correspondingly-threaded lower end of an upright post h.Said post is centrally and longitudinally bored to receive the stern fof the valvefand provides a slide way therefor, and at its top, whichprojects above the plane of the top of the cup (1, said post has at oneside parallel ears 2' 1', adapted to receive between themselves the endof a leverf, a pin j being passed through said ears i and end ofthelever to serve as a pivot. The upper end of the valve-stem f projectsabove the top of the post h and is slotted or forked, as at f to receivethe leverj, adjacent to its fulcrumal point, said lever extend= ingoutward over the edges of the cup at to any desired distance and beingprovided at its side with graduating-marks and having a movable weightk.

The valve f is provided at the lower end with a disk-shaped end Z,recessed at its under surface to receive a gasket m, of rubber or thelike. This rubber-faced diskis adapted to be pressed against the upperend of the stand-pipe a by the lever 7' and effect a closure of saidupper end. When, however, the pressure of gas in the cask becomes sufiiciently strong, it will raise the lever j and bpen the valve f,permitting an escape of the gas, as will be understood. To provide forthe escape of said gas, there is preferably formed in the walls of thetubular valve-incasement g and near its bottom a perforation n, saidperforation opening into a vertical passage 0, formed in an integraladdition 0, cast at the side of the valve-incasement g. These openingsand passages described thus allow the gas to escape and bubble upthrough the liquid in the cup d, and, furthermore, permit thelubricating fluid in said cup to reach the valve to prevent its becominggummed with saccharine matter, as usual.

Having thus described the invention, What I claim as new is- 1. In apressure-regulating valve, the combination of a stand-pipe, a cup-likecasting, open at its top, supported upon said standpipe and having itsbottom perforated and receiving the end of said stand-pipe, a valveclosing the end of said stand-pipe and having a stem extending upward,an integral valvechamber projecting upward from the bottom of thecup-like casting and surrounding the said end of the stand-pipe and thevalve therefor, a post extending upward from the top of said chamber andbeing centrally hollow to receive the valve-stem, and means for normallyholding said valve closed, substantially as set forth.

2. In a pressure-regulating valve, the com-.

bination of a connecting-pipe exteriorly threaded near its end andhaving a stop-cock back of said threaded end, a cup-likecasting havingits bottom perforated and interiorly threaded to screw upon said pipe, avalvechamber projecting integrally upward from the floor of saidcup-like receptacle and having an opening through one side, a tubularpost secured at its lower end to the top of said valve-chamber, and avalve comprising a stem workin g in said tubular post and a lower enduprightstem working in said center post, substantially as set forth.

4. In a pressure-regulatin g valve, the combination of a connecting-pipeexteriorly threaded near its end, a cup-like casting havin g its bottomexteriorly provided with an annular extension interiorly threaded toscrew upon said pipe, the bottom of said cup being perforated and theend of the pipe projecting therethrough, an interior valve-incasementprojecting integrally upward from the floor of said cup-like receptacleand having a passage through one side, a tubular post screwed at itslower end into the top of said valve-incasement, a weighted leverfulcrumed at the upper end of said post, and a valve comprising a stemworkingin said tubular post and a disklike lower end recessed at theunder side to receive a gasket and adapted to close the end of theconnecting-pipe, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this20th day of April, 1899.
